T0 ALL WHOM IT MAY CONCERN: v

Beit known that I, ANSELAMO B. SMITH, of Plattsmouth, in thecounty ot Cass, and State of,Nebraska., have-invented a. new and useful Improvement in Carriage-Wheels; und Ide hereby declare that the following is nfull, clear, und exact description thereof, which 'will enable others skilled in the art to make and use the sume, reference being had -to the accompanying drawings, forming part of this specification.

This invention consists in a novel nndimprovcd manner of securing the spokes 'of wheels in a. metallic hub, and in a. peculiar construction of the hub, whereby n. ve'ry strong und durnblefwheel is obtained, undone which muy haveits spokes adjusted to compensate. for any shrinkage thereof, so os to avoid theloseuing of the tire,

and the necessary shrinking' of the s ame, whiclrkis now required inwhe'e'ls as ordinarily constructed. In the accompanying sheet of drawings- I Figure 1 is a, sidc'sectionnl view of my invention, tuken'in the linea: z, 2. Figure 2, a. central section ofthe same, taken in the line y y of fig. 1. Figure 3, a section of the same, taken in the line z z, fig. 2. Similar letters of reference indicate corresponding parts. 4 I A represents vthe spokes of a. wheel, and B the rim thereof. The rim may be exclusively of-metal, or itrm'ny be of wood, and provided with a metal. tire. The outer ends ofv thespokes have round tenons, a, ent on them. to fit inrholes or mortises in the inner sido of the rim, and the inner ends, b, of the spokes are of taper or wedgeshspe in n direction transverse with the axle of the wheel, as shown in fi'g. 1, so that said ends b muy bel tted snugly together in'close contact. These ends b, at their other sides, which nre in planes longitudinal with the axle, are of dove-tail' form, as shown clearly in iig. 1.

The metal hub of the wheel is composed of a. tube, C, provided with o.l collar, D, which' is of concave i'orm at its'inner'side, that is to soy, the side which abuts ugeiustA the spokes, (see 2,) and this concave surface4 corresponds to the bevel or inclination of the lends b of the spokes, whichbevc'l or inclination forms the dovetul thereof. i

On the tube C, some distance from the collar D, there is cut n. screw, c, to receive a nut, E, and the tube C, between'tlie collar D und the screw c, is of conical or taper form, and has a. band,d,iitted upon it, said band being out in order thnt it may t snugly on the tube. This tube is passed through the circular opening formed" at the inner ends of the spokes, said ends bearing against the band d, and the spokes are firmly-retained between the two cellars D and u loose coller, F, which is p ressed up irinly against the spokes by the nut E.y

.'.llic dove-tail form of the cnds b of the spokes, in connection with the concave collar D, eifectually prevents the shifting or moving of the spokes in n. longitudinal direction, and in case of the shrinking of the spokes,

or 'of the rim, in @use a. wooden one 'be used, the spokes muy bc adjusted outward to tighten them and the tire by placing a. thicker band, d, on the tubo C. v

The hub is.retained on the wheel by having o. groove, e, cut inthe outer end o'f the axle G to receive a. key or slotted disk, II, (sce figs. 2 and 3,) the key or sl'otte'd disklbeing retained in position by a screw-cap, I, en thc end of-tube G, us shown clearly in tig. 2. i

Having thus described my invention, what/I claim as new, and desire to secure by Letters Patent, is` l. The whccl, consisting ofthe bevellcd and dove-tniied spokes b, with the inner inclined ends resting upon the collar d, surrounding the tube C, and secured in place against the concave collar G by means of the loose collar F und nut E, all constructed as described, for the purpose specified.

2. I further claim the securing of the hub on the axle by means of the slot e in the axlc G, the keyor slotted disk 1I, und the screw-cap I, allarrungcd substnntiully as and for the purpose specified.

The shove specification of my invention signed by me, this 14th day of September,l1867.
